concrete mortar Rebound enhancer
Baiqiang Brand BY-2016 concrete mortar reinforcing agent, also known as Rebound King, is a water-soluble liquid chemical hardener with colorless and transparent appearance. The main components of concrete surface reinforcing agent are reactive alkali metal silicate or modified alkali metal silicate, catalyst auxiliary Etc., concrete surface reinforcement alias: concrete seal curing agent , liquid floor hardener, cement Ground sanding agent, ground penetrant, concrete penetrant, etc.
Principle: Top 100 brand BY-2016 concrete surface strengthening agent has low surface tension, which can quickly penetrate into the concrete and react with calcium hydroxide, a by-product of cement hydration in the concrete, to generate a large amount of silicon dioxide Gels, which can block the capillary pores inside the concrete, thus increasing the compactness, compressive strength, hardness and wear resistance of the concrete surface. Generally, the strength of concrete can be improved by 4-10 mpa after spraying. In addition to producing silica gel, this product will also produce some hard and dense substances, which will increase the strength of concrete more significantly. It can harden the cement concrete floor with poor surface strength and ash and sand to be completely free of sand and ash.
Indicator: Test method for abrasion resistance of concrete and its products according to GB/T16925-1997:
Inspection items | technical requirement | Inspection results | Note |
Bending strength 28d, MPa | ≥11.5 | thirteen point two | |
Compressive strength 28d, MPa | ≥80.0 | eighty-three point six |
Wear resistance ratio (%) | ≥300 | three hundred and fourteen |
Mohs hardness | ≥5 | eight |
Scope of application
1. For indoor and outdoor emery wear-resistant floor, terrazzo floor, raw slurry polishing floor, super flat floor, ordinary cement floor, stone and other base surfaces, suitable for factory workshops, warehouses, shopping malls, supermarkets, docks, airport runways, bridges, roads and other cement based places.
2. New and old concrete floors, walls and columns shall be painted to improve the degree and rebound value can generally be increased by 4-10 mpa.
Construction method
1. Before formal use, it is recommended to conduct a small area test on site first, and then use it in a large area after confirming the use effect and dosage (please mix well before application).
2. After the concrete surface is polished and cleaned, open the air hole channel on the concrete surface with one coat of water saturated spraying. After the concrete surface is completely dry for 2-4 hours, spray 2016 concrete surface enhancer (generally once to twice, depending on the effect of the second coat, preferably between 4-12 hours after the construction), and maintain the saturated wet state for 15-20 minutes, To facilitate more effective ingredients to enter the concrete. Saturation curing shall be started for 3 days 4-8 hours after the completion of the second spraying
3. After treatment, the concrete will be effective for 2-3 days, and good results will be achieved in 5-7 days.
4. The tunnel has a good effect. Because of the influence of climate such as environment and temperature, the rebound rate will be delayed to 8-10 days to achieve a good effect.
test : Pre construction test of BY-2016 concrete reinforcer: select one square of concrete area for each: first, polish before spraying a large amount of reinforcer; second, directly spray a large amount of reinforcer, and then cure it after 6-8 hours; at the same time, do rebound test after 1-2 days: carry out construction after confirmation: if the concrete strength deviation is too large, it will not rebound, The next day, a large amount of reinforcer is sprayed twice in the same way. After spraying, the reinforcer is cured for three consecutive days. Note: "During construction, the amount of spraying should be saturated, and the sprayed reinforcer must keep the concrete surface wet for about 20 minutes, so as to achieve good results!" The second spraying is carried out 24 hours later.
